A class-action lawsuit has been filed against Roseau-based Polaris Industries, alleging the company knew or should have known about a serious defect in several of its models that poses a serious fire hazard. It comes three days after the announcement that Polaris will pay over 27 million dollars for allegedly not telling the Consumer Product Safety Commission that some models of its RZR off-road vehicles manufactured between 2013 and 2016 could catch fire. Federal regulators say Polaris had received reports of 150 fires, including one that killed a 15-year-old passenger. The company agreed to an “enhanced compliance program” and says it is “continually… bolstering its safety and quality practices.”
